SPECIFICATION forming part of Letters Patent No. 585,752, dated July 6, 1897.

Application filed November 27, 1896.

T0 ctZZ whom it may concern:

Be it known that I, THOMAS HALLIWELL, a subject of the Queen of Great Britain, residing at Eccles, in the county of Lancaster, England, have invented certain new and useful Improvements in Apparatus for Dyeing, Bleaching, or Scouring Fibrous Materials, of which the following is a specification.

This invention relates to improved apparatus for dyeing, scouring, or bleaching yarn in the form or shape of cops or other fibrous material. It will be fully described with reference to the accompanying drawings.

Figure l is a front elevation; Fig. 2, a plan; Fig. 3, a sectional elevation of part of apparatus through one of the chambers A, drawn to a larger scale 5 Fig. 4, a sectional elevation of part of apparatus through one of the auxiliary chambers O, drawn to a larger scale; Fig. 5, a transverse section; Fig. 6, a sectional plan of part of apparatus on line so at, Fig. 3; Fig. 7, a plan, partly in section, on line 1 y, Fig. 4; Fig. 8, a sectional plan of bottom of vat A.

I construct my improved apparatus with two closed chambers 0r vats A A to receive the yarn-cops or material to be dyed and to contain the liquor with which yarn-cops or other material is to be treated. The chambers or vats A A are preferably cylindrical in shape and are connected at the bottom by a pipe or pipes B, through which the dye or other liquor can fiow from the vat or chamber A to the other vat or chamber A.

On the top of each of the vats or dye-chambers A A, I place a second or auxiliary chamber O 0, extending to a considerable height above the dye-chambers. By means of these auxiliary chambers the dye-vats A A are connected to an ejector D or to an air-pump or other exhauster, by which a vacuum or partial vacuum may be produced in either of the dyechambers A A to fill them with dye liquor or to cause the dye liquor to flow from one to the other through the bottom pipe B.

The upper chambers C 0 act as condensers to condense and collect any steam or moisture drawn off from the dye-chambers A A. They are each provided with a central passage or chamber fitted with a number of tubes 0, extending throughout its length, through which the air and vapor are drawn off by the ejector or exhauster D, and with a number of side passages E, preferably four, each divided longitu- Serial No. 613,610.

dinally into two parts by a division-plate 6. Cold Water is caused to circulate around the pipes c, entering at theinlet-pipe 0 near the bottom and flowing out by an outlet-pipe 0 near the top, for the purpose of condensing any vapor or steam that may be drawn up into them by the exhauster or ejector D.

The side passages F. at the top at one side of the division-plate 6 open into the chamber 0, which is also in communication with the pipes c, and at the other side of the divisionplate are joined or connected with one another with a chamber a, in which any moisture carried up through the pipes o collects and from which it can be drawn off. At the bottom of the chamber e below the side passages E is fitted a discharge-pipe c fitted with a suitable valve 6 Fig. 5, through which any water of condensation or liquor therein can be drawn off and returned to the vat A. This valve works automatically when the pressure in the vat A is below that in the chamber c. The chamber 6 is also fitted with a gage-glass c to indicate the amount of liquor collected therein.

The side passages E and the condensingchambers G O are connected with the exhaust or ejector D by means of the pipes F F and the valve G, working in the valve-chamber H.

The valve G is constructed with a central port g, so as to be capable of placing each of the vats AA, through the chambers O 0, side passages E, and pipes F F, alternately in connection with the exhaust or ejector D and with the external atmosphere. The valve-chamber H is provided with three ports. Two of these ports, ff, connect and communicate with the exhaust-pipes F F, one at each side, and the third one, it, connects with the exhaust or ejector D by the pipe cl. When the valve G is at one end of the chamber H, (see Figs. 4 and 5,) the portf is brought into con1- munication with the port it and with the exhaust or ejector D, and the port f is uncovered and is open to the atmosphere, so that air can pass through it into the pipe F, and when moved to the other edge of the chamber H the port f is brought into communication with the port h and the exhaust or ejector D, and the port f and pipe F are opened to the atmosphere. When the valve G is placed in the center of the valve-chamber H, both ports ff are closed.

The valve G is worked to and fro by hydraulic pressure by means of a piston K, Working in a cylinder L, to which water is admitted through the ports Z Z. The piston K is connected to the valve G by the piston-rod 7c. The water to operate the piston K is supplied from a main water-pipe M through the watersupply valves m m.

The valves m m, which supply the-water to the cylinder L, are operated or opened alternately by floats N in the interior of the vats A A. Each float N is connected by means of a connecting link or lever n with a spindle n, which projects through the side of the vat and which is forced outward when the float N rises, coming into contact with the spindle of the water-supply valve m and opening the valve. The valve m is held closed by a spring. The valves m m have each double ports, and when the inlet-waterway is closed the exhaust is open, through which the exhaust-water from the back of the piston flows away.

Each of the vats A A is fitted on top with a hinged lid or cover 0, which is held down in position when closed by a screw 0, engaging with and operating two pivoted levers 0. When the screw is lowered, the ends of the levers 0 are forced out under the edges of the top, and when the screw is raised the ends of the levers are withdrawn.

In the interior of each of dye vats or chambers A A is fitted a false bottom or plate P, above the inlet 1) of the pipe B, through which the liquor is admitted. The bottom or plate P is provided with a number of (preferably four) openings 19, over or upon each of which is placed a plate or carrier R, upon which on hollow skewers the cops of yarn T are placed. The plate P is also provided with a valve 13, which can be opened and closed from the outside of the vat by the handle 19 through which liquor may be allowed to pass either up or down when required.

The cop carriers orplates R are each formed with an upright handle r, by which they can be lifted into and out of the vat. They are held in position in the interior of the vat by a lever S, pivoted to side which rests on the top of the handle r, and depending arms 8 therefrom rest on the edges of the plate or carrier R. The pivoted lever S is secured by the double or jointed links 5, pivoted to the top. The cop-carriers R are lifted into and out of the vats by means of a hook r, attached to a chain passing over a pulley and counterweighted at the other end, the pulleys being supported on a swiveling arm W, as shown in Fig. 1.

On the handle 7" of t he cop-carrier R is placed a plate T, which rests upon the top of the hollow skewers or spindles in the interior of the cops T and holds the cops in position.

The pipe B, which connects the two dye chambers or vats at the bottom, also serves as a means of communication for introducing the dye liquor or for supplying water or steam to the dye-vats A A. At the back of the maintained closed while the apparatus is at work and is opened to supply the dye liquor to or discharge it from the vats A A. On the top of the bottom pipe B, I attach a waterpipe V, with a valve V, through which Water can be introduced into the vats A A to wash the cops, and in front I attach a steam-pipe WV for introducing steam into the vats at the bottom to steam the cops. Another branch of the steam-pipe W conveys steam to the ejector or exhauster D.

A steam-coil w is placed in the interior of the vats to heat them to the desired temperature. These coils are connected by the steampipes to and the valves 10 and the waste steam escapes at the discharge-pipe 10 The two vats A A are also connected at top by means of a pipe Y with a branch y extending to the valve-chamber, in communication with the ejector or exhauster D and fitted with a three-way valve y. By means of this pipe and valve both vats can be exhausted at the same time for the purpose of filling them with liquor or for drawing air or steam through the cops.

In operating the apparatus the cops of yarn T on the top carriers R are placed in position in the interior of the vats A A over the apertures p in. the bottom P and secured by the levers S and links 8, and the lid is closed. The stop-valve U on the pipe B is then opened to admit the dye liquor, and the ejector or exhauster D is set in operation, the valve G being set in a central position to close ports ff, which lead to the vats. The three-way valve 1 in the pipe Y is next opened, placing the ejector or exhauster D in communication with the vats A A and the exhaust or vacuum therein slowly draws up the dye liquor into them until there is sufficient. The stop-valve U and the three-way valve 3 are now closed and the valve G moved to one end of the valve-chamber H, putting the port f in communication with the exhauster or ejector D, thereby creating a vacuum in the vat A and drawing the liquor from the vat A until it reaches the height of the float N and raises it. The rising of the liquor and the raising of the float N (see Fig.6) in the vat A forces or moves out the spindle n, which projects through the side until it'comes into contact with the spindle of the water-supply valve m and admits water to the other side of the piston K in the hydraulic cylinder L and reverses its position and causing the valve G to move from one end of the chamber II to the other and changing the exhaust from the vat A to the vat A. By this arrangement the working of the vats is rendered automatic. As soon as the position of the valve G is changed the exhaust is applied to the other vat and the liquor then flows back through the pipe B until the operation is again reversed in a similar manner. This movement of the liquor from one vat to the other forces the liquor through the'cops T first in one direction and thenin the reverse. The air and vapor drawn off from the top of the vat A passes through the pipes 0, around which cold water is circulating, in which any steam or vapor is condensed, thereby assisting the formation of the vacuum, and thence up the side passages E of the auxiliary chamber 0 to the pipe F, any condensedwater which may be carried over from the pipes c collecting in the cham-. ber c at the bottom. The liquor is discharged from the vats again by opening the stop-valve U. Steam is admitted into the vats when required by the steam-pipe W and water from the water-main V through the valve V.
